With its low installation cost and high accuracy, GPS has become an essential method in the field for tectonic motion let alone location decision. In this study, data obtained from IGS stations between 2004 and 2012 analyzed using precise point positioning. Monitoring of tectonic motion demonstrates that the Antarctic continent behaves as a rigid plate. The speed vector for each station decided based on the GPS data processing result showed that Antarctica rotates around the Mawson and its rotation speed was calculated as about 0.001” per year on an X-Y plane. The processed GPS results were compared with other models for verification and suggested the Tectonic Motion of Antarctica precisely. It is expected that the tectonic motion of Antarctica can be used as the basic data on various scientific purposes.
